    How can I fix a stuck bleeding radiator valve?


    I have a radiator which seems to have a stuck bleeding valve. I want to let some air out, but the valve won't budge. There has been no change to the radiator itself or how we’ve been using it recently, so I’m not sure what could have caused it to be so tight recently.
    Are there any usual causes for the valves getting stuck? Could I fix this myself?

    "Hi try a little WD40 first option, if this doesn't work then the bleed valve will have to be replaced altogether, and if the valve still wont come out then the radiator may need replacing although this could be down to why you have got the problem in the first place depending on the age of the radiator cheers Craig"

    "You can either persevere and try to use long nose pliers to remove the bleed valve and replace it, or you may have to replace the section with a new bleed valve insert if it’s possible. If neither of these are available to do, you would have to replace the radiator."

    "Hi. Firstly I would say get a Gas engineer or plumber in just in case you face complications if doing it yourself. However, if you still insist on wanting to give it a try then try WD40 or you can buy new bleed valves from Screwfix, You need to turn the valves off both sides of the radiator and then change them. Please be careful. Hope that helps."

    "Would recommend that you have plumber come have a look because if you snap the bleeding nut could end up having 1.5 bar of pressure going all over the floor"

    "It may be stuck because it has never been used and the water has made it hard to open. You would need to drain the radiator and replace the whole bleed valve with a new one."

    "Close the valves on both sides of the radiator. Then loosen the whole bleed valve with a spanner making sure you have something underneath to catch the water. Once the water has stopped running from the valve take it out and replace with new. Then bleed the radiators of air."
